BROODER Filed Nov, 12. 1931 '35 Figure 3 shows a horizontal sectional Patented Aug. 29, 1933' The object of my, invention isto `'providea brooder of simple, durable and inexpensive construction so arranged and combined that a water` container is located close to the floor to permit 5 chicks to pass under it, and4 so arranged that the water in the container may berthrermorstatically controlled to maintain a predetermined degree of heat, and that the air surrounding the water `container may be thermostatically controlled to, .10 maintain a different predetermined amount of heat. g 1 v t O A further object is to provide a broodergof this character in `Wh-ich,lfrorn `a single down-draft burner, the productsofcombustion may belpassed through or in close contact withthe water to,

heat it, 01 it may be passed by the more direct route to the flue. so that a different'proportion ofthe heat from the burner maybe applied to the air surrounding the watercontainer.` c

120 A further object is to provide thermqstatical-f ly controlledmeans whereby the temperature of the water in the container may bethermostatically controlled by theadmissionof Coldwater.

Figure 5, shows a detail view partly in section ymission of cold water into the waterrcontainer; and i A Figure 6 shows a detail end view illustrating the float and its controlling lever.

Referring to the accompanying drawing, I have used the reference numeral 10 to indicate a Water container or pan, supportedton legs l1 spaced apart from the iioor far enough to permit chicks to enter under it." These legs are preferably ad? justable so that the height ofthe water `container from the floor may beregulatedas desired.

A coldwater pipe 12 entersthe pan through a ball valve 13 lof ordinary construction, specifically shown in Figure Y5, and this ballv valve, is

My inventionv consists in'` theconstruction, ar- 1 illustrating the float controlled valve for the adcontrolled by ia oat 14 of ordinary construction,

the partsvr being so arranged that' when "the fioat moves upwardly toward a` horizontal position, the ball valve is closed, and when the float moves vdownwardly tothe position shown in Figure 5,

the -ballv valve is open to vpermitv the fflow of-.60` cold water into the water` container. There isalsoa water overflow pipe' 15. v e `Mounted within the water pan is a thermo-, stat device-v 16 of ordinary construction connected to a lever 17, which lever is `also extended .65

over the iioat valve 14. These parts are so are ranged that iwhenthe 'thermostatdevice `16 ex@ pands, due to excessive heat ofthewaterythe float ispulled downwardly and cold water admitted into the lcontainer. 70

The heater body is indicated generally by the ,Y reference numeral 18 ,and is provided with a central-cylindrical air inlet` iiue 19, and a vdischarge flue 20'.r A horizontally arranged partition 21 vdivides the body intoupperandlower sections,

and the lower section is provided with deector Walls 22 substantiallyU-shaped andV extending from the down-draftiiue 19-1to a point spaced i apart fromthe adjacent side of the body; as shown in Figure 4,y and the productsoficombusn-v v tion pass around the interior of the `under section `of the bodyto the openings 23 in the hori- Zontal partitionZl, and then pass upwardly `and forwardly, `being directed bythe, upright partitions 25. through the opposite side of ,the body, 85 and then they move toward each other and'across the central portion ofthe upper `compartment of the body to theV discharge iiue 20.` f r .i g

, This entire arrangement of the ,various passageways within lthe body is simply for the vpur- 904 pose of causing the products of combustion-to have a fairly long travel before passing tothe ue, 'so` asgto retard the maximum amount vof heat from the products of combustion before* passingtotheflue, r 95 When. starting the oil burner it is desirablelto L have. a short directI passageway to the iiue, and

`for ythat purpose Ihave provided anopening in burner is made the subject matter of a cofpendin'g 195 A application of mine, filed February 9, 1931,'Serial t Number 514,527, and is not herein specifically illustrated or described,` butfor the purposefof this application may be considered simply as a down-` draft oil burner. 110

VrI'he saidbody 18 is preferably supported upon a circular rim 27 fixed to the body and extended A fuel `supply pipe for oil leads to the `and is indicated by the reference numeral 29,

and is in` communication with a regulating vvalve 30 of ordinary construction, controlled by a lever 31,'which lever is automaticallycontrolled ,by a thermostat device 32 inthe air surrounding the Vwater container. l a In a brooder it is desirablethat a place beV provided Where chicks may enter, and which space will be constantly heated'to a temperature of about 105 F. It is also desirable that the air surrounding this space be constantly maintained at a temperature of about 85 F. and for the pur'-I pose of constantly providing these two-diiferent enter underrand close-to its bottom, a single heattemperatures, regardless of the atmospheric conditions to which thebrooderv issubiected at times, I have providedthe following mechanism.

In the bottom of the body 18 I provide a pipe 33, one end opening into the-passageway between the Walls 22 and then extended downwardly through the water-into the water container and having its upper end extended upwardly through ,the vbottom of the body l18 into the interior of the lower compartment of Vsaid body, as clearly shown in Figure 1, and immediately above the inlet Aopening of this pipe '33 is a valve 34 connected tothe 'rod 35, which rod is connected at its upper end to a lever 36, andr this lever is connected by a rodf3'7 with a thermostat device Y38 located in the water in the container. v

Y Q'Ihese parts'are so arranged that when the water in the'container is heated beyond a certain predetermined degree thethermostat device 38 expands and pushes the valve v34: downwardly l0v parallel with the bottom of the body 18, closing the passageway through the pipe 33, so that all of the productsof combustion Vpass through the -body 18, The major portion of the heat from the `,burner serves to heat the air surrounding theV water container. f Y

When, however, the temperatureV of the water in theA container falls below the predetermined amount, the thermostat device 38 contracts and opens the valve Bi'to the position shown in Figure l 1, and-causes the major portion of the products of combustion from the burner to -be deflected downwardly through the pipe 33, so that its heat is applied directly to the water, and the temperature ofthe water is quickly raised to the desired point without-havingfso much ofthe heat from the burner applied to the air surrounding the body A'hover 39 may be applied above ythe body 18, if desired.V V

` In practical use the amount of fuel applied to the down-draft burner isthermostatically controlledin the ordinary way, thus controlling the size of the flame fromrthe burner. When starting' the brooder,`and assuming that the water is cold, the valve 34 will be in its upwardly inclined position Vand will direct the major portion of the products of combustion through the pipe 33, and thus quickly bring the temperature of the water upto the desired point. When this has beenreached the valve 34 is automatically closed and the major portiony ofthe products of combustion heat the surroundingair by radiation Vfrom the Vbody 18, and when the' temperature surrounding the air t reaches a certain predetermined amount, it 'is regulated by the thermostat device which autoburner Lezazov maticallycontrols the supply of fuel to the burner. In the event that the Water in the container should at any time exceed the predetermined degree of heat, Vit is automatically 4cooled to the desired point bythe thermostat device 16 operating the float 14 to admit cold water.

By thisl arrangement it will lbe seen that I have rounding the water pan may at the same time be Constantly maintained at a much-less temperature, and that there are no rapidly owing currents of air either in the spacev under the water container or in the space surrounding the body 18.
